Bone Mineral Density in Women With Major Depression
Summary
The purpose of this study is to examine calcium absorption and bone mineral density in women with depression.
Research indicates that pre-menopausal women with depression have significantly lower bone mineral density (BMD) than pre-menopausal women without depression. Although the mechanisms of BMD loss are unclear, researchers believe that individuals with depression have impaired calcium absorption. However, it is unknown whether the abnormal absorption is a result of depression or a side effect of the drugs used to treat it. This study will compare calcium absorption in women with depression and in healthy women without depression.
Participants in this study will be given two non-radioactive calcium isotopes. One can be taken by mouth and the other must be injected. Participants will have the level of isotopes in their urine measured to estimate true fractional calcium absorption (TFCA). Participants may also have a dual X-ray absorptiometry (DEXA) scan to measure total body adiposity and lean body mass.
Description
Osteoporosis is a condition that is underdiagnosed and undertreated, and often goes unnoticed until a fragility fracture occurs after many years of progressive loss of bone quality. Risk factors for osteoporosis include glucocorticoid excess and a pro-inflammatory state, both of which we and others have observed in a substantial proportion of patients with Major Depressive Disorder.
We have found statistically and clinically significant reductions in bone mineral density (BMD) in a group of 24 depressed but otherwise healthy pre-menopausal women, as compared to 24 healthy, closely matched controls. The difference was significant at several trabecular bone sites (e.g., 13.6% at the femoral neck, 13.6% at the Ward's triangle, and 10.8% at the trochanter). Epidemiological studies indicate that losses in trabecular bone mineral density of these magnitudes are associated with an increased lifetime risk for fracture up to 50%.
Although the mechanism(s) of the lower bone mineral density in our patients with past or current depression has not yet been elucidated, these subjects showed significantly higher 24-hour urinary free cortisol excretion than their matched controls. However, the extent of the lower bone mineral density in women with past or current depression cannot be accounted for strictly on the basis of hypercortisolism alone, but is likely to require other hormonal or biochemical factors as well.
Preliminary data in subjects recruited from a large study of mothers with or without mood disorders and their offspring indicate that a disproportionate number of young adult offspring of mothers with Major Depressive Disorder show reduced BMD, 2/3 of whom had not yet manifested clinical signs or symptoms of mood disorder.
In the light of the fact that major depression affects between 5% and 9% of the female population, the depression-associated lower bone mineral density potentially predisposes millions of women to enhanced susceptibility to osteoporosis. We therefore wish to continue our assessment of bone mineral density in subjects with past or current depression to further document the incidence of lower bone mineral density in a larger series. We also wish to identify subjects with past or present depression who have reduced bone mineral density to offer them the possibility of participating in other studies designed to clarify pathophysiologic mechanisms involved in low bone mineral density, identify any clinical characteristics of depressive illness that may predict increased risk of osteopenia or osteoporosis, examine the association of low BMD with other endocrine and metabolic disturbances seen in depressive illness, and to identify those who may require therapeutic intervention.

Medical and Biotech [MESH] Definitions
Healthy People Programs
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Nutrition Policy
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
Nerve Transfer
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Surgical Clearance
Process of evaluating the health of a patient and determining if they are healthy enough for surgery.
Healthy Diet
Dietary patterns which have been found to be important in reducing disease risk.
